A few points of polish

[PimpUigi]

I'm having a blast playing through Doom 32XCD and I can't tell you how motivated this has made me to enjoy Classic Doom again.
So I'm making my way through on Nightmare! and lol, it sure is harder than I remember 32X Doom. :D

A handful of things stand out to me though...all fairly small, don't worry about hurting my feeling if you disagree with or can't address them in programming, but thank you for taking the time to read what I'm putting down. : )

In the order I encounter them in game:

1. I figure the reason for the difficulty name changes is to save ROM space?
   I'm Too Young To Die is just about as iconic a name as Nightmare! is and I remember laughing so hard as a kid when I first read that. So I figure since I'm A Wimp is shorter, it saves sprite space? Like taking out the Hey in Hey Not Too Rough? Now that we're on CD format though, is it possible to get the OG difficulty names back?

2. The Gray surrounding Doomguy's portrait is noticeably brighter than in the PC ports, and it was just jet black in 32X Doom so that jumped out at me. It should be changed to 27,27,27 or whatever is currently available in palette that is closest to it. (I see plenty of colors on the HUD to choose from that are very close)
   

3. This issue is more prevalent to me than any of the others: Gun bob seems to not be as smooth as 32X Doom was. Not sure if it's just less ticks per frame? But even when the game is running at 30fps I feel like each frame of the gun bob is longer.
   Wait! I can frame count this! OK...
   4 ticks of bob per frame in Doom Fusion.
   3 ticks of bob per frame in vanilla 32X Doom.
   Strange I notice that? Of course over a 30 frame animation that's 12 extra frames, it's about a 60 frame animation (very rough estimate) so that's roughly half a second longer to complete a single left to right weave.
   Oh...it's going way further to the sides in vanilla 32X Doom. Much further distance per frame. It must be the combination of those two things making it feel a lot smoother in the OG 32X rom.
   See these comparison screenshots showing the maximum distance to the far left for the handgun:
   
   

4. Mode + Face Button is a great way to hot swap weapons! Well done on implementing that, but it seems to me that the HUD spots for the guns should match the face buttons.
   X = Handgun Y = Shotgun Z=Chaingun
   A = Rocket L. B = Plasma C = BFG 9000
   This was how I was intuitively trying to do it because of the HUD in game vs. the controller layout.

5. The sound effect when you hit the Exit switch doesn't play. I know that's likely a technical limitation due to loading etc. but I was hoping you could push back the call to cut away from the level until that sound finishes playing?

6. The shocked face feels like it appears too often. I'm getting the shocked face when Handgun Soldiers shoot me, and from single Imp Fireballs, just to name the two most out of place times. Generally what I'd consider weak attacks. Could the threshold be increased? I'd think for how rare the face originally appeared something like 50% damage and up moments?

The numbers font in the Intermission still has the shadow from the HUD. (guessing to save ROM space from when the game wasn't CD format)

The font is stored in the ROM, we can't afford having multiple fonts there.
